WhatsApp has become one of the most popular messaging apps, with over 2 billion users worldwide. One of the conveniences of WhatsApp is being able to restore your chat history when you get a new phone or reinstall the app. However, many users have experienced frustration with how slow the WhatsApp restore process can be. There are several factors that contribute to the slow restore speeds.
Large chat history size
One of the main reasons WhatsApp restore takes so long is due to the sheer size of chat histories. WhatsApp by default backs up your entire chat history including media to either Google Drive or iCloud. This backup can quickly grow in size, especially for those who have used WhatsApp for years and exchanged lots of photos, videos, and files.
For example, a user who has actively used WhatsApp for 5 years could easily have a backup greater than 5GB in size just for their chat history. Trying to download and restore a backup this large will understandably take a lot of time.
Media heavy chats
Chats that contain a lot of shared media such as photos and videos will be much larger and take longer to restore. Media files take up significantly more storage space than simple text messages. Even if you don’t have a long chat history, if you frequently exchange high resolution photos and videos your backup will be larger.
Here’s a breakdown of how much storage different media formats typically take up:
| Media Type | Size Range |
|---|---|
| Text message | 1 – 100 KB |
| Photo | 500 KB – 10 MB |
| HD Photo | 2 – 20 MB |
| Video (1 minute) | 10 – 50 MB |
As you can see from the table, just a few HD photos and videos can significantly increase the size of your backup.
Connection issues
The speed of your internet connection also plays a major role in how fast WhatsApp can restore your chats. Restoring chats requires downloading your full chat history backup over the internet from iCloud or Google Drive.
If you have a slow internet connection, have poor reception, or are trying to restore while connected to public WiFi then the entire process will take longer. WhatsApp can only restore as fast as your connection allows it to download your backup.
Here are some approximate WhatsApp restore times based on connection speed:
| Connection Speed | Restore Time (for 1GB chat backup) |
|---|---|
| 2G | 12+ hours |
| 3G | 3-5 hours |
| 4G | 45-60 minutes |
| Broadband (25 Mbps) | 8-10 minutes |
| Fiber Optic (100 Mbps) | 2-3 minutes |
Server issues
There can also be issues on WhatsApp’s server side that cause slow restore speeds for some users. WhatsApp likely uses content delivery networks (CDNs) to deliver chat history backups around the world. Sometimes these servers can become overwhelmed and introduce latency when fetching your backup.
WhatsApp restores are also dependent on Google Drive and iCloud availability. If either cloud storage service experiences an outage or high traffic volumes it can impact restore speeds as well. Issues on WhatsApp’s side or with their cloud storage partners can degrade performance.
Encryption overhead
WhatsApp uses end-to-end encryption for chat histories and backups. This provides important security and privacy protections for your conversations. However, encrypting and decrypting your chat history also introduces computational overhead into the restoration process.
Encrypted data requires more processing to encode and decode during transit compared to plain text. This necessary encryption can slightly prolong the time it takes to complete a restore, but is a worthwhile tradeoff for better security.
Tips to speed up restore
While some WhatsApp restore slowness is inevitable for the reasons explained above, there are some steps you can take to improve the process:
Delete old chats
Regularly trim your WhatsApp chat history and delete very old chats you no longer need. This prevents your backups from getting too huge over time. You can manually delete chats or enable auto-deletion in WhatsApp’s settings.
Use WiFi for restore
When possible, restore chats only when connected to WiFi and avoid using mobile data. WiFi is much faster than mobile connections.
Free up storage space
Make sure you have ample free storage space on your phone before restoring chats. Low storage space can slow down the restore process.
Force stop other apps
Close out all other apps on your phone while restoring to allow WhatsApp the maximum bandwidth. Other network activity can interfere with restore speeds.
Try late at night
Restoring chats late at night or early morning may be faster as there is likely less traffic on WhatsApp’s servers. Less congestion improves speeds.
Be patient
Understand that WhatsApp restore for a large chat history simply takes time. Be patient and plan the restore when you don’t need access to WhatsApp for a while. Let it run in the background until completely finished.
Conclusion
WhatsApp restore takes time due to the combination of large chat backups, media sizes, connection issues, encryption overhead, and server loads. While the process can seem slow, remember WhatsApp is transferring your entire chat history. The most practical solution is being selective about keeping your chat history trimmed to a reasonable size. Also utilize WiFi and low-traffic times when you need to restore your chats.
With billions of users worldwide backing up their chats, WhatsApp faces inevitable challenges in making restorations consistently fast for everyone. However, the convenience of being able to fully restore your chat history outweighs the slow speeds. Hopefully WhatsApp continues improving the restore process while keeping user privacy and security as top priorities.
Frequently Asked Questions
Why does WhatsApp backup take so long initially?
The initial WhatsApp backup takes a long time because the app needs to upload your entire chat history and media to iCloud or Google Drive. This can be GBs of data and takes hours on slower connections. Subsequent backups only upload new chats and changes.
How can I speed up future WhatsApp backups?
You can speed up backups by clearing large media, deleting old chats, using WiFi instead of mobile data, and enabling low quality backups in settings. Smaller incremental backups complete faster.
Is there any way to skip media during restore?
Unfortunately, WhatsApp does not allow selectively restoring only chats or only media. You must restore everything together. The only option is pausing the restore and then resuming when ready.
Does WhatsApp optimize media during backup?
Yes, WhatsApp does apply some optimization to media like compressing photos and videos during backup. But very high resolution media will still increase backup size significantly.
My chats are missing after restore, how can I get them back?
If you notice certain chats are missing after a restore, first ensure the backup completed 100%. If chats are still missing, you may need to restore from an older backup that still contained the chats.
